The Alligator Plant (Kalanchoe daigremontiana) is a distinctive succulent, also known as Mother of Thousands or Mother of Millions. Its elongated, fleshy leaves have serrated margins where tiny plantlets readily develop.
Essential Care for Your Alligator Plant
Light
The Alligator Plant thrives in bright, indirect light. Place it near a south or west-facing window, avoiding harsh direct sun that can scorch its leaves. Insufficient light leads to leggy growth and reduced plantlet formation.
Watering
Allow the soil to dry completely between waterings to prevent root rot. Water thoroughly until it drains from the pot’s bottom. During cooler winter months, reduce watering significantly, perhaps to once every few weeks.
Soil
A well-draining soil mix prevents waterlogging. Use a commercial succulent or cactus potting mix, or amend standard potting soil with perlite or coarse sand. Good drainage is essential for root health.
Temperature and Humidity
Alligator Plants prefer average room temperatures, typically 65-75°F (18-24°C). They tolerate typical indoor humidity and do not need high moisture. Protect them from cold drafts and temperatures below 50°F (10°C), as they are not frost-hardy.
Fertilizing
Fertilizing is not a frequent requirement. During active growth in spring and summer, feed monthly with a balanced liquid fertilizer diluted to half strength. Avoid fertilizing during fall and winter when growth slows, as over-fertilization can harm the plant.
Propagation and Managing Growth
The Alligator Plant propagates easily from small plantlets that develop along its leaf margins. These miniature plants, complete with roots and leaves, detach readily from the parent.
To propagate, collect fallen plantlets and place them on well-draining soil. They will root and establish as new plants, often filling nearby pots or growing within the same container.
Managing this rapid proliferation is important. Regularly remove excess plantlets to prevent overcrowding. If grown outdoors in suitable climates, their widespread self-seeding can make them invasive. Responsible management is advised to control their spread.
Troubleshooting Common Problems
Browning leaves often indicate too much direct sunlight or inconsistent watering. Adjusting light exposure or refining your watering schedule can resolve these issues.
Yellowing leaves may indicate overwatering, leading to root rot, or nutrient deficiencies. Ensure the soil dries between waterings; consider diluted fertilizer if nutrient issues are suspected. Pests like mealybugs or aphids can infest the plant. Wipe them away with a cotton swab dipped in rubbing alcohol or use a mild insecticidal soap.
Important Safety and Environmental Notes
All parts of the Alligator Plant (Kalanchoe daigremontiana) are toxic if ingested, posing a risk to pets and young children. Place the plant out of reach to prevent accidental consumption.
In warm, frost-free climates, Kalanchoe daigremontiana can become invasive if planted outdoors, outcompeting native flora. Avoid planting it directly in garden beds. Dispose of excess plantlets and old plants responsibly to prevent establishment in natural environments.
